Why is this?arrow_forwardLactose in milk is hydrolyzed, absorbed through the intestines, and then utilized for energy metabolism. Oligosaccharides that are not hydrolyzed in the digestive tract cannot be absorbed nor used for energy. Choose the best explanation for why these oligosaccharides would be necessary in human milk (or infant formula). A) These oligosaccharides prevent weight gain in infants. B) These oligosaccharides absorb excess energy, allowing infants to sleep. C) These oligosaccharides train the digestive tract to tolerate high levels of sugars, necessary for a typical adult American diet.
